Airag, (Fermented horse milk) is a traditional milk product in Mongolia. Herders separate foals from their dams and tie them at a milking site during the daytime to produce airag. To evaluate the effects of horse management on the movement of dams, we tracked three dams in a herd in camp 1 during summer and camp 2 during autumn of 2013 and analyzed their movements during the milking (daytime) and non-milking (nighttime) periods in an area famous for its high-quality airag. Dams were gathered every 1.7 ± 0.0 h between 07.46 and 15.47 hours at the milking sites and milked 4.6 ± 0.2 times/day during the study period (86 days). Daily cumulative and maximum linear distances from the milking sites were longer (P < 0.01) during the non-milking period than during the milking period. Daily home ranges were 91 and 26 times greater during the non-milking period (P < 0.001) in camps 1 and 2, respectively. The greater range during the non-milking period would reflect the spatial distributions of water, salt and forage. The dams initially used similar areas and gradually shifted their daily home ranges after several days. This shift suggests that the dams grazed farther afield as forage availability declined around the milking site. For better airag production and sustainable pasture use, our results provide insights useful for evaluating the effects of milking management on vegetation and soil in those pastures, for selecting the appropriate milking times and frequency, and for choosing the right timing to shift milking sites.

为蒙古发酵的马奶生产挤奶的水坝运动。

Airag(发酵马奶)是蒙古的传统牛奶产品。牧民白天将小马驹与大坝分开,并在挤奶场将它们绑在一起以产生气息。为了评估马匹管理对水坝运动的影响,我们在2013年夏季的1号营地和2年秋季的2号营地的一群牛群中追踪了三个水坝,并分析了挤奶(白天)和非挤奶(夜间)期间它们的运动在以高质量airag闻名的地区。在挤奶地点的07.46至15.47小时之间,每1.7±0.0小时收集一次水坝,在研究期间(86天)每天挤水4.6±0.2次/天。在非挤奶期间,距挤奶地点的每日累积和最大线性距离要比挤奶期间更长(P <0.01)。在1号营地和2号营地的非挤奶期间,每日房屋范围分别增加了91倍和26倍(P <0.001)。非挤奶期间的较大范围将反映水,盐和饲料的空间分布。这些大坝最初使用相似的区域,并在几天后逐渐转移其日常居住范围。这种转变表明,由于挤奶场周围的草料供应量下降,大坝向更远的地方放牧。为了更好地生产空气并可持续利用牧场,我们的结果提供了有用的见解,可用于评估挤奶管理对这些牧场中植被和土壤的影响,选择合适的挤奶时间和频率以及选择转移挤奶地点的正确时机。非挤奶期间的较大范围将反映水,盐和饲料的空间分布。这些大坝最初使用相似的区域,并在几天后逐渐转移其日常居住范围。这种转变表明,由于挤奶场周围的草料供应量下降,大坝向更远的地方放牧。为了更好地生产空气和可持续利用牧场,我们的结果提供了有用的见解,可用于评估挤奶管理对这些牧场中植被和土壤的影响,选择合适的挤奶时间和频率以及选择转移挤奶地点的正确时机。非挤奶期间的较大范围将反映水,盐和饲料的空间分布。这些大坝最初使用相似的区域,并在几天后逐渐转移其日常居住范围。这种转变表明,由于挤奶场周围的草料供应量下降,大坝向更远的地方放牧。为了更好地生产空气和可持续利用牧场,我们的结果提供了有用的见解,可用于评估挤奶管理对这些牧场中植被和土壤的影响,选择合适的挤奶时间和频率以及选择转移挤奶地点的正确时机。这种转变表明,由于挤奶场周围的草料供应量下降,大坝向更远的地方放牧。为了更好地生产空气和可持续利用牧场,我们的结果提供了有用的见解,可用于评估挤奶管理对这些牧场中植被和土壤的影响,选择合适的挤奶时间和频率以及选择转移挤奶地点的正确时机。这种转变表明,由于挤奶场周围的草料供应量下降,大坝向更远的地方放牧。为了更好地生产空气并可持续利用牧场,我们的结果提供了有用的见解,可用于评估挤奶管理对这些牧场中植被和土壤的影响,选择合适的挤奶时间和频率以及选择转移挤奶地点的正确时机。
